SPECIFICATION forming part of Letters Patent No. 713,660, dated November 18, 1902.

Application filed April 15, 1902. Serial No. 103,051- (No model.)

To aZZ whom it nuty concern:

Be it known that I, EDWARD E. MANNING, a citizen of the United States, residing at Belvidere, in the county of Boone and State of Illinois, have invented certain new and useful Improvements in Sewing-Machine Cabinets, of which the following is a specification.

The object of this invention is to construct a sewing-machine table or cabinet in which the flexible band and rollers usually employed are done away with and positive devices employed.

In the accompanying drawings, Figure 1 is a plan view of a table, showing my improve ments. Fig. 2 is a lengthwise vertical section. Figs. 3 and 4 are transverse vertical sections.

The table or cabinet comprises the top 1, frame 2, coverS, and back. Aplatform comprises the sections 5 and 6, hinged together, and the section 5 is hinged to the frame 2 along one side of its central opening. The cover 3 is hinged to the frame. To the back 4 is secured a support 7 and to which is pivoted a bell-crank lever comprising the arms 8 and 9. A link 10 has one end pivoted to the arm 8 of the bell-crank lever,and its other end has a pivotal connection with a bracket 11, secured to the under face of the cover near the hinged connection between the cover and frame. To the back at is hinged a toggle-lever composed of the arms 12 and 13, hinged toget-her and the arm 12 hinged to the back. The arm 13 has its free end-in fork form and pivotally connected to the under face of the section 5 of the platform. A turnbuckle 14 has one end connected to the arm 9 of the bellcrank lever and its other end connected to the arm 12 of the toggle-lever, thereby forming a connection between the bell-crank lever and toggle-lever and also a connection between the cover 3 and the platform. A coiled spring 15 has one end connected to the arm 9 of the bell-crank lever and its other end connected to a stationary part of the table. A spring 16 has a connection with the section 5 of the platform and bears against the other section of the platform.

At Figs. 1, 2, and 3 the platform is shown in its elevated position and the cover open, and in Fig. 4 the platform is dropped and the cover closed.

In opening the cover the link 10 will move the bell-crank lever on its pivotal connection with the back, and through the turnbuckle the toggle-lever is raised, which will raise the platform and hold it elevated. The spring 15 will assist in raising the platform and the machine-head supported by the platform. In closing the cover the platform will be dropped, and the spring 15 will prevent the too-sudden descent of the platform. By this arrangement as the cover is moved a positive movement is imparted to the platform in raising and lowering the platform.

I claim as my invention-- 1. In a sewing-machine table, the combination of a table-top, a hinged platform and a hinged cover, a double-link connection between the platform and a stationary part of the table and a connection between one of the links and the cover.

2. In a sewing-machine table, the combination of a table-top, a hinged platform and a hinged cover, a double-link connection between the platform and a stationary part of the table, a bell-crank lever havinga pivotal connection with a stationary part of the table, a connection between one arm of the bellcrank lever and one of the links, and a connection between the other arm of the bellcrank lever and the cover.

3. In a sewing-machine table, the combination of a table-top, a hinged platform and a hinged cover, a double-link connection between the platform and a stationary part of the table, and an adjustable connection between one of the links and the cover.
